Abstract
Packaging pads comprise top and bottom sheets laminated together along peripheral surface portions with a pocket of comminuted filler material centrally disposed between the sheets. Apparatus for manufacturing the pads continuously feeds an endless bottom sheet along a predetermined travel path, and liquid adhesive is applied to the upper surface of the sheet as it so travels. A stream of filler material is divided into spaced apart individual pocket amounts and these filler amounts are joined to the adhesive coated surface of the bottom sheet. A top sheet coated with liquid adhesive on the underside thereof is laminated onto the bottom sheet and the pocket amounts of filler material. The thus formed continuous laminate is transversely cut midway between adjacent pockets of filler material to thereby form individual packaging pads.
